Answer 1

[AI-generated answer — Bot GPT 3.5]

1. OCl^-: In this anion, oxygen is more electronegative than chlorine and will take a charge of -2. Therefore, the oxidation number of chlorine in OCl^- is +1.

2. ClO2^-: In this anion, oxygen is more electronegative than chlorine and will take a charge of -2. Therefore, the sum of the oxidation numbers must equal -1. Since there are 2 oxygen atoms with a total charge of -4, the oxidation number of chlorine in ClO2^- is +3.

3. ClO3^-: In this anion, oxygen is more electronegative than chlorine and will take a charge of -2. Therefore, the sum of the oxidation numbers must equal -1. Since there are 3 oxygen atoms with a total charge of -6, the oxidation number of chlorine in ClO3^- is +5.
